APPARATUS FOR COOLING ENGINE-CYLINDERS.

SPECIFICATIN forming part of Letters Patent No. 643,065, dated February6, 1900.

Application led April 20, 1899- To all whom t may concern:

Be it known that I, JOHN W. LAMBERT, a citizen of the United States, anda resident of Anderson, county of Madison, and State of Indiana, haveinvented certain new and useful Improvements in Apparatus for CoolingEngine-Cylinders, of which the following is a specification, referencebeing had therein to the accompanying drawings, in which- Figure 1 is aside elevation showing a portion of an engine-cylinder, thecooling-tank, and the blower; and Fig. 2 is a vertical sectional view ofthe cooling-tank.

This invention relates to that class of apparatus covered by my formerapplication bearing Serial No. 655,454; and it has for its object toprovide certain improvements thereon which are hereinafter more fullydescribed and are particularly pointed out in the claims appended.

Referring to the various parts by numerals, 1 designates a gas-enginecylinder which is provided with a water-jacket of any desired Leadingfrom the top of the water-jacket upward to a tank 2 is a waterpipe- 3,through which the water which has passed through the jacket and becomeheated passesup to the tank. This tank is supported at a suitable heightabove the cylinder, and the pipe 3 opens therein through the bottom.Secured within the tank to the bottom thereof to register with the endof pipe 3 is a vertical tubular casing 4, which extends slightly abovethe water-level in the tank and is of substantially the same diameter asthe pipe 3 and is practically a continuation thereof, the pipe 3 and thecasing 4 forming the hotwater-conducting conduit. Carried by this casingat diametrically-opposite points are two upward-extending arms 5, whichterminate above the water-level in the tank.

Surrounding the tubular Casin g and extending a short distance above theupper end is the inner end of the pipe 6, through which a blast of airis driven by a blower 6, operated by the engine or other suitable means,said pipe carrying at its upper end the outward and downward extendingdeflector-plate 7. Connecting together the upper ends of the two arms 5is a bridge-bar 8, whose center Serial No. 713,807. (No model.)

portion is raised 'and lits closely within the cylindrical hood 9 and ispermanently attached thereto, said hood being formed with the invertedconical top 10.

The tubular casing 4 is formed at its bottom with a bearing l1 toreceive the lower end of the rotary-screw water-elevator 12, and thebridge-bar 8 is formed atits center with a bearing 13 to receive theupper end of this water-elevator, said water-elevator extending throughthe casing 4 and serving to lift the water in said casing over into theblast-pipe 6. Secured rigidly to the water-elevator just at the top ofthe blast-pipe is a small motor or fan-wheel 14, which receives theblast of air and is rapidly rotated thereby. A pipe 15 leads the coldwater from the bottom of the tank to the lower portion of theengine-cylinder jacket.

In operation the water in the tank and in the tube 4 is at the samelevel when the engine is not running. When the engine is started, theblower is put into operation and a blast of air is forced through themotor-fan, thereby rotating it and with it the screw Water-elevator. ASthis elevator is operated it lifts the water from the casing 4 over intothe blast-pipe, from which it is blown up through the fan and into thehood 9. From the hood the water drops to the deliectorplate '7 andfinally falls into the tank 2. It will thus be seen that positive meansis provided for causing a rapid circulation of the water, the means forcausing this circulation being operated by the blast which sprays andcools the water.

It will be observed that a feature which contributes to the utility ofthe apparatus lies in the fact that the blast of air carrying theoverflowing water is thrown violently against the blades of the motor,whereby the water will be finely sprayed and intermittently commingledwith the blast of air and thereby quickly cooled.

I claim- 1. In an apparatus for cooling engine-cylinders, or the like,the combination of a water-tank, a cool-water pipe leading from the tankto the device to be cooled, a hot-water pipe leading from said device tothe tank and IOO extending up into the tank to near the Waterleveltherein, a blast-pipe entering the tank and terminating adjacent theupper end of the hot-Water pipe, so that the blast Will strike the Wateras it overiows from the hot-Water pipe, a blower, an air-motor supportedabove the hot-Water pipe and blast-pipe, in the path of the blast, and awater-lifting device supported in the hot-Water pipe and attached to andoperated by the air-motor, whereby the blast will take up the Water asit overiiows from the hot-Water pipe and spray it against the air-motor,for the purposes set forth.

2. In a cylinder-coolin g apparatus the combination of a cylinder andWater-jacket therefor, a water-tank, a hot-Water conduit connecting thejacket to the tank, said conduit extending near to the Water-level inthe tank, a Water-elevating device with the hot-Watery conduit, ablast-pipe surrounding the end of the hot-Water conduit, means forcausing a blast therethrough, and means wherebyT the air-blast willoperate the water-elevating device to lift Water from the hot-Waterconduit into the blast-pipe and the airb1ast will spray and cool theWater, said means for operating the Water-elevating device beingsupported in the path of the blast at the upper end of 'the blast-pipe,above the upper end' of the hot-Water conduit, so as to receive andbreak up the spray and commingle it with the blast.

3. In a cylinder-coolin g apparatus the combination of a cylinder andWater-jacket therefor, a Water-tank, a cool-Water pipe leading from thetank to the jacket, a hot-water conduit leading from the jacket to thetank, said conduit extending near to the Water-level in the tank, ablast-pipe surrounding the said conduit, a rotary Water-elevator Withinthe hot-Water conduit, means operated by the airblast to rotate saidelevator to lift Water into the blast-pipe, said means consisting of anopen air-motor to receive the impact of the blast and lifted Water andintimately commingle the same.

4:. In a cylinder-coolingapparatus the combination of a cylinder andWater-jacket therefor, a Water-tank, a cool-Water pipe leading from thetank to the jacket, a hot-Water conduit leading from the jacket to thetank, said conduit extending near to the level of the Water in the tank,a blast-pipe surrounding the hot-Water conduit, a rotary Water-elevatorWithin the hot-Water conduit, afan or similar air-motor secured to theelevator and operated by the air-blast, said fan being journaled orsupported above the hot-Water conduit and in the path of the blast,whereby the lifted Water will be thrown against the fan-blades and breakup the spray and commingle it With the blast.

5. In a Water-cooling apparatus, the combination of the device to becooled, such as a gas-engine cylinder, a Water-tank, a cold-Water pipeand ahot-water pipe connecting said tank with said device to be cooled,said hotwater pipe extending to a point above the normal Water-level ofthe tank, a blast-pipe surrounding the upper end of the hot-water pipeand extending above the same, a Waterelevating screw j ournaled in theupper end of the hot-Water pipe, an air-1notor carried by the shaft ofsaid screw at a point above the hot-Water pipe, in the path of the blastof air and hot Water, means for supporting the screw shaft, and meansfor returning thc sprayed Water to the tank, substantially as set forth.

In testimony whereof I hereunto affix my signature, in the presence oftwo Witnesses, this 18th day of April, 1899.
